Genesis G80 vs G90: Performance, Features, and Price

The Genesis G80 and G90 fit different needs and budgets. One’s a sleek midsize sedan, while the other’s a full-size flagship, but both pack the refined engineering that’s made Genesis a real challenger to other luxury brands. In this Genesis G80 vs. G90 comparison, our team at Genesis of Columbia breaks down their performance, tech, features, and price. By the end, you’ll know which one matches your driving life better.

Comparing the Genesis G80 vs. G90: What You Need To Know

The first difference you’ll notice between these two luxury sedans is their size. The G80 measures 196.7-197 inches long, 75.8 inches wide, and 57.7 inches tall, with a 118.5-inch wheelbase. The G90 stretches 207.7 inches long, 76 inches wide, and 58.7 inches tall, with a 125.2-inch wheelbase. That extra length means more interior space, though both fit five adults comfortably.

MotorTrend ranked the Genesis G80 No. 4 among luxury midsize sedans while crowning the G90 No. 1 in luxury full-size sedans for 2025. Each sedan targets different competitors. The G80 battles the BMW 5 Series, Mercedes-Benz E-Class, and Audi A6, while the G90 competes with the Mercedes-Benz S-Class, BMW 7 Series, Lexus LS, and Audi A8. For Columbia buyers, the G80 offers luxury sedan entry, while the G90 delivers maximum prestige and comfort.

Engine Power and Performance Differences

The G80 starts with a turbocharged 2.5-liter four-cylinder making 300 horsepower and 311 lb-ft of torque on 2.5T models. 3.5T trims add a 375-horsepower twin-turbo 3.5-liter V-6 that gets 391 lb-ft of torque. The V-6 goes from 0 to 60 mph in 5.1 seconds, while the four-cylinder takes 5.7 seconds.

The G90 offers two engine choices. The standard G90 3.5T AWD produces 375 horsepower and 391 lb-ft of torque from its 3.5-liter Twin-Turbo V-6. The G90 3.5T E-SC MHEV AWD and 3.5T E-SC Prestige Black AWD use a 48-volt e-Supercharger to deliver 409 horsepower and 405 lb-ft of torque, with a 0-to-60 mph time of 5.1 seconds. This supercharger setup provides power on demand with better efficiency.

Fuel economy differs between models. The G80 2.5T AWD achieves 20 mpg city and 29 mpg highway compared to the G90 3.5T AWD’s 18 mpg city and 26 mpg highway. Both use eight-speed automatic transmissions, but the G90’s includes Predictive Shift tech that uses sensors and navigation for smoother shifts.

Interior Comfort and Cabin Features Compared

Let’s compare the G80 vs. G90 luxury features inside the cabins. The G80’s interior includes leatherette seats, gloss black trim, power front seats with four-way lumbar, and heated seats front and back that are perfect for those chilly Columbia mornings. Higher trim levels add real wood finishes and nappa leather diamond-stitched seats with contrast piping.

The G90 takes luxury to another level with features that match cars costing way more. You get nappa leather seats standard, real wood trim, plus heated and cooled front seats with massage built in. The 18-way power seats let you find that perfect driving position, while the massage seats with four custom modes and 10 air pockets make long drives feel more comfortable.

Rear-seat comfort is where the G90 really stands apart. An 8-inch screen in the armrest lets back-seat passengers adjust their seat position, turn on massage, set their own climate, change the mood lighting, and even move the window shades. It’s perfect for Columbia executives who need to impress clients or families who want everyone to ride in style.

Rear-Seat Space and Ride Quality

The G80 offers plenty of space for most needs. Front seats have loads of head and leg room, while the back seats fit two adults comfortably for trips around Columbia. You get 13.1 cubic feet of trunk space, plus some extra storage bins and a pass-through for long items. That’s enough for groceries, luggage, or golf clubs for a day at one of Columbia’s courses.

The G90’s extra length means seriously more space inside, especially for back-seat riders. This makes it ideal if you’ve got teens, regularly drive clients around, or just want your passengers to stretch out. Long trips to Charleston become luxurious experiences instead of cramped car rides.

These cars also differ in ride quality. The G90’s sophisticated air suspension automatically adjusts height and stiffness to smooth out bumpy roads and stay stable at highway speeds. This tech is a godsend on Columbia’s mix of smooth new roads and rougher city streets.

Tech and Safety Features

The G80 features a massive 27-inch OLED display that handles all digital functions. It includes wireless Apple CarPlay and Android Auto for easy phone connectivity. The big screen combines gauges and entertainment, reducing distractions.

The G90 adds flagship tech features. You get four power doors that open and close automatically, fingerprint login, Genesis Digital Key 2 for phone-as-key functionality, and Remote Smart Parking Assist 2 that parks while you watch from outside. The optional Bang & Olufsen 3D sound system delivers amazing audio through 26 speakers and dual amps.

Both cars feature impressive safety tech, including forward collision-avoidance assist, blind-spot collision-avoidance assist, lane-keeping assist, driver attention warning, Smart Cruise Control, and automatic high-beams. Both also feature Highway Driving Assist 2, Blind-Spot View Monitor, and Safe Exit Assist, which warns about approaching traffic when opening doors.

Starting Prices For The Genesis and What You Get for the Money

The G80 starts at $57,100 for 2025 models and ranges from $58,450 to $79,350 for 2026 versions. The 2.5T Advanced trim offers excellent value, adding 19-inch wheels, a panoramic sunroof, ventilated front seats, three-zone climate control, a power trunk, and a Bang & Olufsen stereo.

The G90 starts at $89,700 for 2025 models and $92,700 for 2026 versions. While pricier than the G80, it includes luxury features standard that cost thousands extra on competitors. If you’re looking for financing, please contact our finance center to explore additional Genesis financing options.
